The invention teaches a kit-like system and apparatus for dispensing a multiple component reactive material from two cartridges each having an exteriorly threaded semi-cylindrical outlet nozzle, where the respective components need not be mixed together immediately, but only in close proximity of the intended use of the material. Thus, the cartridge nozzles will be spaced from one another, and at least one will be paired up with a dummy nozzle having a like exteriorly threaded semi-cylindrical nozzle, but with no outlet. Special universal fittings are provided in the kit that fit over the paired cartridge and dummy nozzles, and over a separate conventional mixer, and further that allow for hoses to be connected thereto, to define separate component flow paths from the separate cartridges to the remotely located mixer and then to the intended discharge location. A clamp on the common discharge flow path can be used for regulating the material discharged from the component cartridges proximate the end use location.

This is a Continuation-in-Part application of application Ser. No. 09/392,752 filed on Sep. 7, 1999, now 6,129,249 which is a Continuation Application of application Ser. No. 08/740,096 filed on Oct. 24, 1996, which has been allowed and is now U.S. Pat. No. 5,984,152 issued on Nov. 16, 1999.
A dispensing device and method, especially adapted for use in sealing high pressure fluid leaks, is disclosed. Such use requires high pressure dispensing of sealant. Such sealants are formed by an exothermic reaction of at least two liquid substances that generates high pressures within the dispensing device. Such pressures could potentially harm the feeding system of the device due to pressure backflow. This problem is solved by providing a check valve in the mixing and reaction chamber of the device to protect the feeding system. A static mixer is disposed within the chamber to enhance mixing and reaction of the substances.
A method of separately storing, mixing, combining and dispensing reactive two component materials by employing the use of a rotary stop cock that is formed so that in a first selected position it can separate a plurality of compartments, in a second selected position can allow for the flow of material from one or more upstream compartments into a downstream compartment, while also allowing air to vent from the downstream compartment through the stop cock and out to the atmosphere, and in another selected position can allow for the flow of material from what was the downstream compartment to what was the one or more upstream components without venting any of the compartments.
